Flight Test of scaled MTEs for VTOL Certification using an Ultralight Coaxial Helicopter
Proceedings of the Vertical Flight Society 78th Annual Forum, 2022New methods are currently being investigated to perform certification of future electric Vertical Take-Off and Landing (VTOL) aircraft. Due to the expected mission requirements, classical certification methods do not lend themselves to this type of vehicle.

Inflight Measurements of the Empennage of an Ultralight Coaxial Helicopter
Proceedings of the Vertical Flight Society 81st Annual Forum and Technology DisplayThe empennage of a helicopter is largely responsible for its stability in forward flight. Its performance is mainly determined by its aerodynamics. In this paper, the empennage of a CoAX 2D ultralight research helicopter is analyzed in detail.

Airborne Acquisition of Blade Tip Displacements and Vortices on a Coaxial Ultralight Helicopter
33rd AIAA Aerodynamic Measurement Technology and Ground Testing Conference, 2017A series of comprehensive flight tests investigated the flight dynamics and explored the flight envelope of a newly developed ultralight, coaxial, counter-rotating helicopter from the company edm aerotec. The present paper focuses on optical measurement techniques that were applied to study the minimum blade tip clearance and convection of blade ...

Model-Based Optimization of a Tethering Device for Ultralight Helicopters
Proceedings of the Vertical Flight Society 78th Annual Forum, 2022This paper presents the process of flight mechanical analysis and optimization of a helicopter tethering frame that is used in pilot training and research projects. An existing linear state space model of the CoAX 2D ultralight helicopter is fusioned with a parametrized analytical model of the tethering device. Using the eigenvalues of the free

Simulator-Based Evaluation of Visual Pilot Assistance for Coaxial Ultralight Helicopters
Proceedings of the Vertical Flight Society 79th Annual Forum, 2023This paper presents a flight simulator study that examines whether a display inside the cockpit can aid helicopter pilots with little to no experience in completing basic maneuvers. The study participants have no prior experience as helicopter pilots.

Stability Augmentation System for Coaxial Ultralight Helicopters
Proceedings of the Vertical Flight Society 76th Annual Forum, 2020In this paper, the concept, design and implementation of a stability augmentation system for coaxial ultralight helicopters is presented. For an exemplary realization, the CoAX 2D ultralight helicopter is used. It is a 2-seated helicopter with two teetering mainrotors in a coaxial configuration with a maximum take-off mass of 450kg developed by
